This is my second extension cord (refurbished first) and like other TP-Link devices it works great. So far there hasn't been a difference between a new example and a refurbished one - apart from the cost๐ I live in a one story house and an extension cord on each end results in a very strong signal throughout the house. The WPA security gives me a little more confidence that the imaginary child next door isn't spying on the system too often.
